Will human beings' selfish acts bring about the Earth's doom?
Ans: Of course it will bring about the Earth's doom. At that time, it is too late to change the past and only regret about one self's selfish acts.
What we can we do to save the Earth?
Ans: We could ride a bike to school or work.
Turn off the lights and water whenever you go out of the room or the bathroom.
Reuse plastic bags. Example: Cover the rubbish bin with a plastic bag to prevent the rubbish bin from getting dirty.
Only use what you need. Do not get more than enough plastic bags because it is free.
TOGETHER WE CAN PLAY A PART, EVEN IF IT IS A TINY LITTLE PART, and if everyone else does too, slowly but surely, we'll save the planet!
